Their bodies were found with their hands and feet tied, their heads covered with cloth atop each other inside a carnapped L300 van Saturday.

Police said the hijacking could have taken place between Feb. 4, the day the L300 van was stolen, and before their bodies were discovered.

The hijacked 18-wheeler trailer truck contained steel bars from the Cathay Pacific Steel Corp. in Napindan, Taguig City. It was bound for San Pedro, Laguna before it was hijacked somewhere in the boundary of Pasig and Taguig, according to police.

The truck remains missing at press time.

Saquilayan said they are still determining the time and place of death, although he noted that the bodies were already in decomposition stage when found.

He said they are still awaiting the release of the autopsy report.

Meanwhile, Saquilayan said that there were no closed-circuit cameras installed near the area where the victims were found.
